Function operation:
The ARCCOS function carries out the operation of the arccosine trigonometric function. The real value is given at input x and then the arc cosine function value is calculated. If the input value is outside the range of the function domain, the error output is activated and the y output is π for x <-1 or 0 for x> 1.
